In Dota 2, deciding when to push lanes is a strategic choice that can lead to gaining map control, securing objectives, and ultimately, winning the game. Here are scenarios and considerations for determining the optimal times to push lanes:

1. After Winning a Team Fight:

• Winning a team fight creates a numerical advantage on the map. This is an ideal time to push lanes, as the enemy team cannot defend effectively. Prioritize lanes with objectives that can be easily taken, like towers or barracks.

2. When the Enemy is Distracted:

• If the enemy team is occupied elsewhere (such as taking Roshan, defending another lane, or dealing with a split push), it’s a good opportunity to push. This forces them to make difficult decisions: contest your push and possibly lose Roshan or let you take objectives uncontested.

3. When Key Enemy Heroes Are Dead:

• The absence of crucial enemy heroes, especially those with strong wave clear or high team fight impact, opens a window to push lanes safely. Keep track of enemy death timers to maximize this advantage.

4. When You Have Superior Vision:

• Good vision around the area you plan to push allows you to see enemy movements and react accordingly. Push when you have wards that provide insight into potential flanking routes or enemy approaches to defend their structures.

5. When Siege Creeps Spawn:

• Every 10 minutes, starting at minute 10, siege creeps spawn in each lane. These creeps deal extra damage to structures and can tank more tower hits, making them valuable assets for pushing.

6. After Securing Aegis or Key Items:

• Obtaining the Aegis of the Immortal or completing significant items (like Black King Bar, Assault Cuirass, etc.) enhances your team’s fighting capability. Use this power spike to push lanes and force fights under favorable conditions.

7. When Split Pushing is Favorable:

• In situations where direct confrontations are unfavorable (due to being behind in net worth or facing a superior team fight lineup), consider split pushing. Heroes that excel in split pushing can apply pressure on multiple lanes, forcing the enemy to split up to defend.

8. Before Important Objectives Spawn:

• Pushing lanes before objectives like Roshan spawn can give your team map control and force the enemy to defend their base, allowing you to take Roshan or set up advantageous fights.

9. When You Have a Push-oriented Lineup:

• Some hero compositions are designed to push early and fast. If your team lineup excels at taking down towers quickly (e.g., with heroes like Pugna, Leshrac, or Beastmaster), look to push lanes as soon as these heroes hit their power spikes.

10. When Enemy Resources are Depleted:

• If you notice the enemy team has used their crucial ultimates or items (e.g., fortification), it’s a strategic moment to push, as their ability to defend is significantly weakened.

Timing and Coordination:

Pushing lanes in Dota 2 isn’t just about brute force; it requires timing, coordination, and reading the game state accurately. Communicate with your team, plan your moves, and always be ready to retreat if the enemy team responds in force. By pushing intelligently, you can secure objectives, starve the enemy of resources, and gradually tilt the game in your favor.
